The difference between "today's task" and "accretive work"

  • AI
  • Programming
  • Developer Tools
  • Startups

The post draws a line between code that solves an immediate problem and code that compounds value over time. It borrows "canonization" from formal math to describe the extra work that turns a one-off result into something general, coherent, efficient, and safe to build on. Doctorow’s AI angle is that large language models make it much cheaper to generate working fragments, but that does not solve the canonization step. In practice, he thinks the business pressure behind AI pushes companies toward "reverse centaurs" who supervise machine output instead of understanding systems deeply enough to make them durable.

Treat AI-assisted code and other fast prototypes as disposable by default, then make an explicit call on whether they are staying. If something is likely to become load-bearing, invest early in boundaries, ownership, and a cleanup pass, because speed at creation does not buy maintainability later.

Discussion mood

Mostly sympathetic to the core idea and skeptical of AI hype. People agreed that one-off code is normal and often useful, but they were blunt that maintainability, ownership, and deletion plans are the hard part AI does not remove.

Key insights

  1. 01

    Design for deletion beats fake permanence

    The useful framing is not "build flexible systems that last forever" but build things that can be killed safely when they outlive their purpose. That shifts modularity from an abstract virtue to a concrete exit strategy. Microservices were cited as one way enforced boundaries can make replacement easier, though the larger point is architectural seams, not any one pattern.

    When you ship a fast solution, decide how it will be removed or swapped out before it spreads dependencies everywhere. Favor interfaces, deployments, and ownership boundaries that let you cut pieces out without a full-system rewrite.

    Spreadsheets are the real baseline

    A lot of software work is already happening in Excel and Google Sheets, with instant feedback and just enough structure to solve a local problem. That matters because it reframes AI coding tools as part of a long continuum between ad hoc end-user programming and formal software engineering, not as a clean break from the past. The bar many quick tools are clearing is not "well-run engineering team" but "a fragile spreadsheet that still runs the business."

    Compare new coding workflows against the actual alternatives inside companies, not an idealized software process. If a task would otherwise live in a spreadsheet, the governance and reliability needs are very different from a core product system.

    Most code should not be overbuilt

    The strongest practical point was that maintainability is not a universal requirement. Code quality should track expected lifespan, transferability, cost of failure, and how likely the logic is to change. Commenters connected this to technical debt as a portfolio choice. Some debt is cheap to carry and easy to abandon, so paying it down is wasted effort.

    Set engineering standards by expected business life, not by professional pride. Reserve heavy abstraction, refactoring, and cleanup for systems that will actually compound or become expensive to change.

    AI raises the value of the canonization pass

    Several comments sharpened the article's business critique. The problem is less the model itself than the assumption that cheaper code generation removes the need for experienced people. If AI floods teams with working fragments, the normalization step becomes more valuable, not less. Someone still has to decide what belongs in the system, what gets simplified, and what stays a local hack.

    Do not plan around headcount cuts alone if you are adopting AI coding heavily. Keep strong technical owners in place for review, consolidation, and system-level design, or the saved time will come back as operational drag.

    Accretive systems can look like hacks for years

    The Sims example adds an uncomfortable truth for managers. Some valuable systems emerge from a long period where they look incoherent, toy-like, or plainly bad. What made that process accretive was not elegant intermediate code. It was the protected tuning phase and the authority of people like Will Wright to keep going until the pieces formed a coherent whole.

    Be careful using early polish as a proxy for long-term value in experimental products. If you are betting on an emergent system, fund the tuning phase explicitly and assign someone senior enough to defend it.

Against the grain

  1. 01

    Same cost faster can still win

    Even if AI does not lower final software cost much, compressing months into days is still commercially powerful. Faster delivery changes time to market, lets companies test internal tools they would never have staffed before, and can create value before maintainability questions even matter. This view treats speed itself as the product, not just a cost input.

    Evaluate AI coding gains on calendar time as well as labor efficiency. In markets where timing matters, shipping earlier can justify workflows that look only marginal on pure code quality metrics.

    Smaller teams may be the bigger story

    One commenter described a production service delivered by a tech lead and one engineer using AI, but the pushback was telling. The improvement may come less from the model and more from removing coordination overhead from oversized teams. If that is true, AI is amplifying a team design lesson many companies already ignore.

    Before crediting AI for dramatic productivity gains, check whether you are really seeing the benefits of fewer handoffs and less review churn. Team topology may deliver more than model choice.

    Canonization is broader than software hygiene

    The idea resonated beyond code as a general knowledge skill. Turning one-off insights into textbooks, libraries, and durable shared resources is rare, undervalued work. Framed that way, the threat is not just messy codebases. It is a world with more raw output and fewer people doing the slow synthesis that makes a field easier to build on.

    Protect time for documentation, libraries, internal platforms, and teaching artifacts. If your organization only rewards immediate output, it will keep generating work without building much leverage.
